Re: [R] questions about histogram

it's a frequency histogram. The total area of the bars is 1, and the area of each bar represents its frequency, i.e. 25/50,10/50,10/50,5/50, respectively. And the width of the bars are different. On Jan 28, 2009, at 5:50 PM, Wenxia Li wrote: Hi all, I'm a new R user.
